How do I perform EDGE Modulation using a Linearized Gaussian Filter using the Communications and Signal Processing Blocksets?

I would like to know if it is possible to do EDGE (Enhanced Data-Rate for GSM Evolution) Modulation which requires using a Linearized Gaussian filter with the help of tools in Communications and Signal Processing Blocksets.

Performing EDGE Modulation requires a very specific form of Gaussian Filter. This can be done in Simulink using the Digital Filter Block from the Signal Processing Blockset. However, care should be taken to give the exact filter coefficients in the Block parameters for this block to get the same functionality as the Linearized Gaussian Filter. More information on Digital Filter Block, type the following at the MATLAB command prompt:

Also, there is a demo “Soft Decision GMSK Demodulator” in the Communications Blockset that you might find useful. You can access this from "Help -> Demos -> Blocksets->Communications->Modulation->Soft Decision GMSK Demodulator.

Observing the way GMSK modulator is configured in this demo model can help you setup your own modulator. Please go through the documentation for this demo. You can access it by typing the following at the MATLAB command prompt:
